CAN-SOLDERING MACHINE.

SPECIFICATION forming part of Letters Patent No. 335,012, dated January 26, 1.886.

Application filed November 16, 1885. Serial No. 312,985. (No model.)

To all whom, '1115 may concern:

Beit known that I, WILLIAM D. BRooxs, of Baltimore, in the State of Maryland, have invented a new and useful Improvement in Gan-Soldering Machines; and I do hereby declare that the following is a full, clear,.and exact description of the same.

My invention relates to machines for soldering the tops and bottoms of provision-cans,

1o known in the art as a iioateri My object in this invention is, iirst, to simplify the mechanism for rotating the revolving table and the can-seats; second, to provide mechanism for soldering the outside of the 1,5 cans; and, third, to retain the heat for the purpose of warming the cans. It also includes details of construction hereinafter fully explained. Y

In the accompanying drawings, Figure 1 is 2o a side view of the machine, partly in section, showing the improved manner of driving the table and can-seats, the shield for retaining the heat being also shown in place. Fig. 2 is a View, mainly in section, with parts in elevation showing modified form of shield used in connection with presser disks. Fig. 3 is a plan View of the table, canseats, shields, 86e. Fig. 4 represents the removable can-seat in position in the flame-chamber. Figs. 5 and 6 3o represent details of the flame-chamber.

In the drawings, A represents a suitable table for supporting the post and operating mechanisms. The post B is fixed in the center of the table in vertical position. Upon it is mounted a continuously-revolving table, C, carrying the rotating can-seats. This table has a sleeve or hub, c, encircling the post and turning on it. The lower end of the hub rests on the table. 0n the lower end of the hub is 4o a beveled gear-wheel, D, xed thereto. On the hub is fixed a collar, d, and this supports the master-wheel E, put in place to revolve around the hub. The master-wheel is provided with a beveled gear, e, on its under surface, of equal diameter with the beveled gear D. The beveled gear-wheel F, on the main driving-shaft f, is in mesh with the beveled gears D and E. The shaft f is mounted in suitable bearings on the supporting-table, and

5o has suitable driving-pulleys on its outer end.

The master-wheel E is in mesh with the pinions g on the lower end ofthe spindles of the can-seats, and the table C is turned continuously in one direction and the master-Wheel continuously in the opposite direction.

The table C is in construction the same as that shown in Letters Patent of the United States granted to me April 4, 1882, No.256,098, and the can-seats are supported on radiallyarranged brackets h, by means ot' spindles 6o which turn iu the sleeved ends of said brackets. Upon the upper ends ofthe revolving spindles are placed spiders z', which support plates k. The can-seatZ is supported within the opening in this plate k by means of shoul- I ders which rest on the edges thereof, as shown. This can-seat is removable, and may be replaced by sizes to suit the larger or smaller cans. A half-wing, 5, supported upon a spider fixed to the sleeved end of the bracket 7o which supports the revolving spindle, forms the rear wall of the can-holder, and is stationary, extending about half-way around. The top of the can-holder consists oli an annular plate, m, supported by posts from the plate 7c, with which it revolves. The can marked M is placed within the opening in the plate m, and rests upon the can-seat Z, as shown in my aforesaid patent, and as the front of the holder is open, a margin of the bottom and side of 8o the can is exposed to the flame directed against it bythe burners or tubes N. The half-wing 5 is cast with an enlargement, 6, on its front ends, With upper and lower bearings, which support intermediate plates, 7 and S. These 85 plates iill the gaps between the upper and lower plates, m lc, of contiguous flame-chambers, and serve to retain the ame while the table is moving successive flame-chambers past the burners. The upper plate is formed 9o with an opening, to allow part of the heat to rise to the warming-chamber. The solderfeeding tube N is supported upon curved bracket-arms n, which extend from the intermediate plates, 7, as shown in Fig. 3. The upper end of this tube is bell-shaped, and the lower end inclined and. beveled to face the side of the can. The platem has a corresponding bevel around theedge of the opening, to admit the end of the tube.

The tube is roo lOl adapted to receive ordinary wire solder, and as its lower end extends down between the inner edge of the plate m and the cam-body, and as close as practicable to the can without interfering with its rotation, it directs the solder against the seam of the top or bottom. It will be understood thatinside soldering may be done also upon this machine, using segmental solder placed within the can. The flame, -impinging against the narrow margin of the side, melts thc lower end of the solder wire, which bears against the flange of the outside headk of the can. As the can turns, the solder is thus laid around upon the seam, and is sweated in by the heat. The arrangement of thist-ube is designed especially for soldering cans having heads fitting the outside of the body ot' the can.

It is desirable that the cans should be kept warmy in order to secure the best action of the solder in the operation of soldering. To effect this, I provide a i'ront and rear shield, O I), suitably supported, and forming a way in which the cans move from, and including the soldering-point, to include also, preferably, the iifth station therefrom. As shown in Fig. l, these shields are connected by the coveringplates I) and are fixed to arms Q, supported on the post. This causes the cans, while under the inlluence of the iiame, supplied, as shown'in Fig. 3, at live points on the periphery ofthe table, to be partially covered, or to pass between walls which are kept warm, and thereby the cans themselves are warmed and in better condition for soldering. The form shown in Fig. 1,which has the top plate, p, is without apresser-plate for holding down the top of the can. This machine, however, is designed for soldering the tops of the cans to the bottoms, and while this is being done the cans4 need not he held downthat is to say, the tops of cans which have holes for the caps are not required to be held down. In soldering bottoms to tops the bottoms are liable to spring and Warp under heat, and therefore they must be held down when in position by means of presser-plates.

A moditied form of machine for this purpose is shown in Fig. 2, the top plate of Fig. l being omitted. The front shield, I?, is supported upon separate brackets q, which are attached to the table. The rear plate, O, is

. supported upon brackets q', fixed to a table,

q2, attached to sleeve R, attached to the revolving table. In this form Iextend the inner shield all the way'around the table5'but the front shield covers only five stations, or the space occupied by the burners. In this form ofthe machine the presser-plates S take the place of the upper plate, p. They are circular in form, and of suiiicient diameter to overlap the shields. They are mounted in pivoted arms T on a table, g2, which are operated by a cam-path, in the usual manner, and as illustrated in Fig. 2. Vhile the presser-plates are down and over the shields, they sufficiently ,lcover the space between the shields to constitute the roof of the chamber for the cans.

The line of movement of the table carrying the can-seats is indicated by the arrow l in Fig. 3, and the arrow 2 in the sameiigure denotes the line of movement of the masterwheel. Three-fourths the way around from the first burner, in the direction of the move' ment of the revolvingtable, I placeadischarging-chute, U, and a discharging-arm, u,which trips the cans successively, and causes them to topple over upon the chute. It will be understood that the arms T are raised by the low part of the cam-path at the proper instant, before the can strikes the arm.

The tube V, with discharge-branches o, may be used for cooling the cans after they leave the shields, being connected with a suitable blower.

Figs.'4, 5, and 6 are enlarged views of the details of construction of the can-seats and the flame-chambers. a

In the operation of the machine, the operator places cans upon the seats as they move past in succession, standing to the lett of the discharge-chute. As soon as the cans reach the warming-chamber, formed by the shields O P, they are acted upon by the iirst burner, N', stationed at the entrance to the said chamber, and in the movement through the chamber are acted upon by the burners in succession, and also by the heat contained within the chamber, and by the time the cans reach the fourth station the solder is entirely melted, receiving the final heat from the fifth station, after which they pass from the warming-chamber to the cooling-tube, and in moving past these stations, of which there are preferably live, as shown, the cans are thoroughly cooled and ready to be discharged at the sixth or discharge station.

I have shown the can-seats as set in an inclined position; but I do not confine myself to this, as I contemplatesetting the can-seats also in a horizontal position for holding the cans vertically.

It will be understood that the revolving ta ble C need not be a plate, but may be made with radial arms, as shown in Fig. 3, one arm being shown for each can-seat.

I claim as my inventionl. In combination with a post, the revolving table O, with its sleeve, a beveled gear, D, the master-wheel'E., meshing'with the pinions of can-seat spindles carried upony said table, and the driving-gearF, in mesh with the gear D, and the gear c upon the under side of said master-wheel, substantially as described.
